JAR-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 674,714, dated May 21, 1901. Application filed February 13, 1901. $eria1 No. 47,133. (No model.)

To all whom, it may concern:

Be it known that I, JOHN SOHIES, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have made certain new and useful Improvements in J ar-Closures, of which the following is a specification.

My invention is an improvement in jar-closures for use in closing jars and the like, and has for an object to provide a simple novel construction which can be readily applied to the jar, will efficiently close the same, and can be easily removed; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a portion of a neck of a jar provided with my improvements. Fig. 2 is a longitudinal section thereof, the cap being shown in the position it occupies before being fastened on the jar-neck. Fig. 3 is a sectional view showing the cap fastened on the jar-neck, and Fig. 4 is a detail perspective view of the cap.

The jar-neck Ais provided within its mouth with a rabbet, forming an upwardly-facing shoulder B, and the lip of the jar-mouth is extended laterally outward and is rounded on its outer side, forming a rounded bead O at the outer side of the mouth of the jar. A gasket D, of rubber or the like, is fitted in the rabbet and rested against the shoulder B within the mouth of the jar and usually proj ects before it is compressed above the mouth of the jar, as shown in Fig. 2. I prefer to employ a liner-disk E, which may be of cork, felt, or glass and rests upon the gasket B and projects laterally beyond the same to rest at its outer edge upon the mouth of the jar, thus providing a portion which bears upon the gasket and an outer portion which bears upon the mouth of the jar, as will be understood from Figs. 2 and 3.

The cap F may be made of thin tin or other suitable material and when ready for use is formed with the top plate F and the rim F depending therefrom and composed of a series of small teeth or points F which are preferably tapered and converge toward their outer ends and are made of a sufficient length to overlap the rounded bead O at the mouth 'of the jar and to be pressed throughout their lengths snugly against the said bead, as shown in Fig. 3 and also in Fig. 1. By preference the central portion of the top plate F is depressed slightly, as shown at f, forming a downward projection, which may operate to increase the outward spring or elasticity of the cap when the same is pressed to sealed position, as shown in Figs. 1 and 3.

' In operation when it is desired to seal the jar the gasket, liner-disk, and cap may be applied, as shown in Fig. 2, and the points or teeth F be bent snugly throughout their lengths around and under the lateral bead O, as shown in Figs. 1 and 3, thus securing the cap firmly in place and causing it to compress the gasket, and thus effect the sealing of the jar, as desired.

To remove the cap, it is only necessary to take an ordinary table-knife or other suitable tool and press back the small points or teeth F un'til enough have been released to permit the cap to be removed. This releasing of the points or teeth is facilitated by their form, they being tapered and converging toward their extremities, which are pressed closely against the under side of the rounded bead and maybe conveniently released by a suitable implement, as before described.

It will be noticed that the spaces or divisions between the adjacent teeth are made of such length as to separate the teeth to the full extent to which they are bent beneath the rounded bead of the jar. This is desirable and important, as it facilitates the bending of the teeth beneath the rounding shoulder and also produces a smoother finish at such point. It will also be noticed that by means of the rabbet B and the use of an annular gasket D, I am able to secure the desired sealing of the bottle by means of a limited size of gasket, the liner-disk being fitted over the gasket and extending beyond the same to bear upon the neck of the jar outside the said gasket, and so ease the bearing of the cap upon the lip of the jar.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A jar or the like, substantially as herein described, having within its mouth a rabbet forming a depressed upwardly-facing shoulder and having its lip extending laterally outward and rounded on its outer sideforming a rounded head at the outer side of the 1 mouthof the jar, and an annular gasket fitted Within the inner rabbet of the jar-mouth, the liner-disk fitting on the jar-mouth over the gasket and extending outside thereof and bearing upon the neck of the jar, and the cap of sheet metal having at its edge the teeth tapering toward their outer ends and bent throughout their lengths snugly against and beneath the laterally-rounded bead of the
